HOLDER FOR SAFETY RAZOR BLADES Filed July 8, 1949 [nun/o z .j 7.2 7. 53w? 279% z'e r10 Patented Feb. 27, 1951 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to an improved razor or blade holder for detachably mounting a safety razor blade and more particularly has reference to a novel construction of holder similar to a conventional straight razor wherein in lieu of a conventional straight razor blade the holder or razor is provided with a mounting structure for detachably mounting a safety razor blade therein and which will effectively function to positively retain the safety razor blade against any movement relatively to the blade holder while in an applied position but which is capable of bein quickly and easily detached from the blade holder or mounting for replacement.

Another object of the invention is to provide a razor having a blade holder or mounting means of extremely simple construction.

A further object of the invention is to provide a razor of a construction similar to a conventional straight razor and which is readily adapted for use by barbers and others desiring or preferring the type of razor known as a straight razor yet which eliminates the need for continuously sharpening the blade by providing a blade holder or mounting from which a conventional type safety razor blade may be quickly and easily removed and replaced when it becomes dull.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating a presently preferred embodiment thereof, and wherein:

Figure 1 is a side elevational view showing the improved razor in a partially opened position and with a safety razor blade securely held therein;

Figure 2 is an enlarged longitudinal sectional view of a portion thereof taken substantially along a plane as indicated by the line 2-2 of Figure 1;

Figure 3 is a viewpartly in section and partly in side elevation taken substantially along a plane as indicated by the line 3-3 of Figure 2;

Figure 4 is a longitudinal sectional view, partly in side elevation taken through the blade holder with the blade and blade retaining member removed, and V Figure 5 is a cross sectional view through th blade holder or mounting taken substantially along a plane as indicated by the line 5--5 of Figure 3.

Referring more specifically to the drawing, the novel razor in its entirety is designated generally 6 and includes a handle, designated generally I formed by corresponding side members 8 which are mounted in spaced substantially parallel relationship to one another by a spacing block 9 which is located between corresponding ends thereof and which is secured thereto by a headed fastening ID.

The blade holder, designated generally H of the razor 6, includes an elongated shank portion, designated generally l2 and which substantially corresponds in shape with the shank of a straight razor blade. The shank portion l2 has a portion, spaced from its shank end, disposed between the side members 8, near their opposite ends and which portion is connected to said side members 8 by a headed fastening it which is rotatably engaged by the shank 12 for pivotally connecting the blade holder H to the handle 1. The shank end l of the shank l2 projects in one direction beyond the handle 1, similar to the shank end of a straight razor blade and is adapted to be engaged by the little finger when the razor 6 is in use, so that said razor'may be held in the same manner as a straight razor.

The blade holder or mounting ll includes an elongated substantially rigid metal strip or bar which is folded upon itself intermediate of its ends as seen at I5 to provide spaced substantially parallel bar portions or plies Hi, portions of which constitute parts of the shank l2. A spacing bar I! is disposed between the bar portions It and is secured thereto by spaced rivets or other fastenings l8. The spacing bar ll combines with contiguous portions of the bars or plies Hi to form the shank l2 and extends from the shank end M to a point spaced from the intermediate bar portion H5. The bar portions l5 and H are of the same width except that the end of the bar l1, located remote to the pivot 13 and adjacent the intermediate bar portion I5, is laterally enlarged as best illustrated in Figures 3 and 4 to define an upwardly extending flange portion 19 and a depending flange portion 28. If desired, the flange portions l9 and 20 and the part of the bar I! located therebetween may constitute a separate element from the remainder of the bar H. The intermediate bar portion Iii and the portions of the bar members I 6 located between said intermediate portion l5 and the adiacent end of the spacing bar I! combine to form an elongated loop 2 I, the elongated slot or opening 22 of which is adapted to accommodate a portion of the blade 23 of a safety razor blade which also includes a head 24 which is formed by an elongated metal strip which is folded lengthwise and clamped around the back edge of the blade 23, as best seen in Figure 5. The upper edges of the bar portions 16, constituting part of the loop 2| are preferably downwardly offset beyond the flange I 9, as seen at 25, and said upper edges 25 are adapted to provide seats for abutting engagement with the two longitudinally extending edges of the blade head 24, as best seen in Figure 5, for supporting the blade 23 in the blade holding loop 2! and so that its cutting edge 26 will be disposed at the same level as the outer edge of the bottom flange 20, as clearly illustrated in Figure 3, so that said flange edge will function as a guard or shield for the inner end of the cutting edge 26.

It will be readily apparent that the blade 23 may be quickly and easily applied to the blade holder loop 2!, as illustrated in the drawing and as previously described, and that the blade head 24 will prevent the blade 23 from moving downwardly through the loop 2| beyond its position as illustrated in Figures 1 and 3. The blade 23 is likewise held detachably in the blade holding loop 2| by a retaining member 21 comprising a strip of metal which is folded upon itself lengthwise and intermediate of its longitudinal edges and which has inturned longitudinal edge portions 28 defining a narrow slot 29 therebetween and which extends from end-to-end thereof. The corresponding sides 30 of the blade retaining member 21 are of a width so that when its intermediate folded or closed edge 3! is in engagement with the outer edge of the blade head 24 and the outer edge of the top flange [9, its inturned edges 28 Will engage the bottom edges of the blade holding loop 2|, as clearly seen in Figure 5. When the blade 23 is applied to the blade holding loop 2|, the upper edge of its head 24 is disposed in the same plane as the outer edge of the top flange l9 and as the blade retaining member 21 is open at each end thereof it will be readily apparent that said retaining member 2! can be slid over the blade holding loop 2! and the blade head 24 and upper flange I9 so that the blade 23 will depend from the holder 2| through the slot 29 of the retaining member 21 and will be held against upward displacement by the retaining member 2! which is retained against upward displacement by its inturned edge portions 28 engaging under the loop 2!. Likewise, the blade 23 is held against longitudinal displacement by the intermediate bar portion [5 at one end and by the adjacent end of the spacer bar ['1 and the flanges I 9 and 20. It will thus be readily apparent that the blade 23 will be securely maintained against any movement relatively to the blade holding loop 2! while the retaining member or clip 2! is applied to afford the maximum of safety to the user; however, by merely sliding the retaining member 21 off of the outer end of the loop 2!, the blade 23 may be quickly removed from the blade holdin loop and replaced by a new blade.

It will thus be seen that a straight-type razor has been provided but which is equipped with a replaceable wafer-thin safety type blade so that a dull blade can be quickly and easily removed and replaced to thereby eliminate the need for frequently sharpening the razor as is required with conventional straight razors. However, the razor 6 can be utilized for all purposes of a straight razor, as for example by barbers who require a straight razor for properly shaving a customer around the ears after cutting the hair.

Various modifications and changes are contemplated and may obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter defined by the appended claims.
